since cpu sets can be dynamically allocated and have variable size, accessing their contents via ->__bits is not valid; performing pointer arithmetic outside the range of the size of the declared __bits array results in undefined beahavior. instead, only use cpu_set_t for fixed-size cpu set objects (instantiated by the caller) and as an abstract pointer type for dynamically allocated ones. perform all accesses simply by casting the abstract pointer type cpuset_t * back to unsigned long *.
musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
